Best Answer

Yes. The X carrying sperm (which are the sperm that make females) live longer than the Y carrying sperm (which are the sperm that make males).
However, the Y sperm swim faster, so the chances are equally good that you will get a girl or a boy. If the Y sperm swim fast enough before they die to fertilize the egg, then you'll have a boy. If the Y sperm don't reach the egg before they die, chances are an X sperm will get there shortly, and then you'll have a girl.
XX makes a girl, XY makes a boy all eggs contain an X chromosome, so sperm donates either an X or Y chromosome.

Girls do not have sperm. If they did, they would not be girls.

There is a sperm for girls. The person is asking if the sperm that makes a baby girl (Y chromosome) lives longer than the sperm that makes a baby boy (X chromosome), not if girls have sperm.
